Yvonne Brill was a brilliant rocket scientist who invented a propulsion system for satellites in the early 1970s and received a National Medal of Technology and Innovation in 2011. Yet her New York Times obituary, published in the newspaper on Sunday, begins like this:
She made a mean beef stroganoff, followed her husband from job to job and took eight years off from work to raise three children. "The world's best mom," her son Matthew said.
But Yvonne Brill, who died on Wednesday at 88 in Princeton, N.J., was also a brilliant rocket scientist, who in the early 1970s invented a propulsion system to help keep communications satellites from slipping out of their orbits.
